我从另一个JFrame类调用的JFrame中插入来自用户输入的数据。我在Oracle 11g快速版中检查了查询，显示没有插入数据。任何人都可以通过在此代码中添加主要方法来修改此查询。JDBC不适用于数据插入？
class Insert extends JFrame{
JLabel name,code,address,telephone,email;
JTextField tname,tcode,ttelephone,temail;
JButton save,exit;
JTextArea taddress;
Insert(){
//properties of frame
super("CUSTOMER MASTER");
setVisible(true);
setLayout(null);
setSize(1100,500);
setResizable(false);
//Initialisation
name=new JLabel("Name:");
code=new JLabel("Code:");
address=new JLabel("Address:");
telephone=new JLabel("Telephone:");
email=new JLabel("E-mail:");
tname=new JTextField();
tcode=new JTextField();
taddress=new JTextArea(4,20);
ttelephone=new JTextField();
temail=new JTextField();
save=new JButton("SAVE");
exit=new JButton("EXIT");
//settingBounds
name.setBounds(10,50,70,25);
tname.setBounds(90,50,150,25);
code.setBounds(300,50,70,25);
tcode.setBounds(380,50,150,25);
address.setBounds(10,100,70,25);
taddress.setBounds(90,100,150,75);
taddress.setBorder(BorderFactory.createLineBorder(Color.BLACK));
telephone.setBounds(300,100,70,25);
ttelephone.setBounds(380,100,150,25);
email.setBounds(10,225,70,25);
temail.setBounds(90,225,150,25);
save.setBounds(900,425,100,25);
exit.setBounds(1000,425,100,25);
//adding on frame
add(name);
add(tname);
add(code);
add(tcode);
add(address);
add(taddress);
add(telephone);
add(ttelephone);
add(email);
add(temail);
add(save);
add(exit);
//ActionListener
save.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent ae){
//getting data from user
String demail,checkdemail;
int dcode,dtelephone;
String dname=tname.getText();
String daddress=taddress.getText();
checkdemail=temail.getText();
demail=validateEmail(checkdemail);
try{
String stelephone=ttelephone.getText();
dtelephone=Integer.parseInt(stelephone);
String scode=tcode.getText();
dcode=Integer.parseInt(scode);
addData(dname,dcode,daddress,dtelephone,demail);
}catch(Exception e){
e.printStackTrace();
}
dispose();
new CustomerMaster();
}
});
exit.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent ae){
dispose();
new CustomerMaster();
}
});
}
public void addData(String name,int code,String address,int telephone,String email){
Connection con;
String str;
PreparedStatement ps;
try{
Class.forName("oracle.jdbc.driver.OracleDriver");
con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","PROJECT","PROJECT");
str="insert into CUSTOMERMASTER values(?,?,?,?,?)";
ps=con.prepareStatement(str);
ps.executeUpdate();
ps.setString(1,name);
ps.setInt(2,code);
ps.setString(3,address);
ps.setInt(4,telephone);
ps.setString(5,email);
con.close();
}catch(Exception e){
e.printStackTrace();
}
}
private String validateEmail(String email){
String vemail=null;
Pattern p1=Pattern.compile("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"+"[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
Matcher m1=p1.matcher(email);
Boolean b=m1.matches();
boolean cb=b;
if(email.equals("")){
vemail=email;
}
else{
if(b==true){
vemail=email;
}
else{
Object message="Enter Valid Email.";
JOptionPane.showMessageDialog(null,message);
}
}
return vemail;
}
}
这里是由SQL开发 代码生成数据库的代码：
CREATE TABLE CUSTOMERMASTER
(
NAME VARCHAR2(20 BYTE) NOT NULL
, CODE NUMBER NOT NULL
, ADDRESS VARCHAR2(50 BYTE)
, TELEPHONE NUMBER
, EMAIL VARCHAR2(20 BYTE)
)

ALTER TABLE CUSTOMERMASTER

插入可能会运行得更好，如果你真的** **执行它：'ps.executeUpdate（）' – Andreas
你需要关闭连接之前执行提交（）。顺便说一句，你的ps.setXXX（）是在'ps.executeUpdate（）;'之后完成的，这显然是错误的。 –
